You could also probably use a free hand and a pen like piece of metal to hold the part in contact, since with the method you do not need to hold a rod of solder in the weak hand.

Other than what you mention the one thing missing is flux. You would need to flux the tube, and the underside of the part. So there is flux between everything in the sandwich. The correct flame is liquid, not noisy, so the part should not get blown away by the flame. Small parts should be no problem with a propane torch. I use Safety silv flux, there are probably better ones, but it works for me.

With tining, what you do is flux the tube, then melt a bit of hard silver solder on it, then let cool, polish or file the flux thin, then flux the solder, and flux the part, and place together, and heat till fused. You can get deal on 56% solder, cad free, on ebay.
